WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to
break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
x Whenever stalled or stopped for repair, move the vehicle a safe distance off the road, stop
the engine, turn on the emergency flashers, and use other warning devices to warn
approaching traffic.
x Never park the vehicle in areas where the hot catalytic converter and exhaust system can
come into contact with dry grass, brush, spilled fuel, oil, or other material that can catch fire.
x A broken down vehicle presents a high accident risk for itself and others. Switch on
emergency flashers and set up a warning triangle to warn oncoming traffic.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
High Intensity Discharge (HID) headlights provide bright, uniform lighting to help you see and be
seen. The light comes from an electric arc between two electrodes in the gas-filled bulb. Over time, the
electrodes can wear down and the gap between them will get wider. The HID lamp’s control unit then
increases the voltage to keep the arc’s brightness constant. However, the commonly called “Xenon”
bulbs will also ultimately burn out. Before they burn out, HID lamps can flicker. A message will then
appear in the MFI. This is your reminder to see an authorized Volkswagen dealer or an authorized
Volkswagen Service facility to check the headlights.

WARNING
Windshield washer fluid without enough frost protection can freeze on the windshield and
reduce visibility.
x Use the windshield washer system with enough frost protection for winter temperatures.
x Never use the windshield wipers/washers when it is freezing without first defrosting the
windshield. The washer solution may freeze on the windshield and reduce visibility.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of accidents and severe
injuries.
x Always replace wiper blades that are worn, damaged, or do not keep the windshield clear.
NOTICE
To help prevent damage to the wiper blades and the wiper motor when it is cold outside,
always make sure that blades are not frozen to the windshield before operating the wipers.
Using the windshield wiper service position can be helpful in cold weather so the wipers do not
freeze to the windshield
Indicator light

WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping
distances.
x Carefully apply the brakes to test them.
x Always dry brakes and clean off ice and salt coatings with a few cautious brake
applications when visibility, weather, road and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stopping distances and can cause
accidents and serious personal injuries.
x Never let the vehicle coast when the engine is switched off.
x If the brake booster is not working (such as when the vehicle is being towed), a lot more
pedal force is needed to slow down and stop.
NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to
brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes
will substantially reduce braking performance, increase stopping distance, and can cause
complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and
shift into lower gear (manual or automatic transmission). This will let the vehicle use engine
braking and reduce the load on the brakes. Otherwise, the brake system could overheat and
possibly fail. Only use the brakes when you need them to slow the vehicle down more or to
stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same
time. The wear of all brake pads should be visually checked regularly. The best way to check for brake
pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility
visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If
necessary, the wheels can be taken off for a more thorough inspection.
Braking assistance systems

Brake fluid specifications
Volkswagen has developed a special brake fluid that is optimized for the brake system in your
Volkswagen. Volkswagen recommends that you use brake fluid that expressly conforms to quality
standard VW Standard 501 14 for optimum performance of the brake system. Check the information
on the container for the brake fluid you want to use to make sure it meets the requirements for your
vehicle.
Brake fluid that complies with VW Standard 501 14 can be purchased from your authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
If this special brake fluid is not available you may – under these circumstances – use another high-
quality brake fluid that complies with U.S. Federal Motor Vehicle Safety Standard (FMVSS) 116 DOT 4
⇒ .
Please note, however, that not all brake fluids that comply with U.S. Federal Motor Vehicle Safety
Standard FMVSS 116 DOT 4 have the same chemical composition. Some of these brake fluids can
contain chemicals that could, over time, degrade or damage internal parts of the vehicle’s brake
system.
Volkswagen therefore recommends that you use brake fluid that expressly complies with VW
Standard 501 14 for optimum brake system performance over the long term.
Brake fluid level
The fluid level in the transparent brake fluid reservoir must always be between the MIN and MAX
marking ⇒ .
On some vehicles, engine components block the view of the brake fluid reservoir and make it
impossible to see the brake fluid level. If you cannot clearly see the brake fluid level in the brake fluid
reservoir, please see an authorized Volkswagen dealer or authorized Volkswagen Service Facility.
The brake fluid level drops slightly when the vehicle is being used as the brake pads wear and the
brakes are automatically adjusted.
Changing brake fluid
Brake fluid must be changed according to the service schedule in your ⇒ Booklet Warranty and
Maintenance. Have the brake fluid checked by an authorized Volkswagen dealer or an authorized
Volkswagen Service Facility. Refill only with new brake fluid that meets the standards listed above.
WARNING
Brake failure and reduced brake performance can be caused by not having enough brake
fluid in the reservoir or by old or incorrect brake fluid.
x Check the brake system and brake fluid level regularly.
x Always change the brake fluid according to the service schedule in your
⇒ Booklet Warranty and Maintenance.
x Hard braking with old brake fluid may cause vapor lock. Vapor lock reduces braking
performance, increases stopping distances and can even cause total brake failure.
x Always make sure that only the correct brake fluid is used. Only use brake fluid that
expressly conforms to VW Standard 501 14 or, if it is not available, only use a high-quality
brake fluid that conforms to U.S. Standard FMVSS 116 DOT 4 requirements.
x Using another brake fluid, or one that is not of high quality, can impair the function of the
brake system and reduce its effectiveness. If the container does not say that the brake fluid
complies with VW Standard 501 14, or U.S. Standard FMVSS 116 DOT 4, do not use it.
x The brake fluid must be new.

WARNING
Improper use of the engine preheating system may cause short circuits, fires, and serious or
fatal personal injuries.
x Always connect the connecting cable to a 120 Volt Ground Fault Circuit (GFI) wall outlet.
The outlet must be protected from water, moisture and other fluids.
x Never connect the engine preheating system to a conventional socket, regardless of
whether the socket is protected or not.
WARNING
Using an outlet or power cables that are incorrect or damaged, using electrical appliances
incorrectly, or ignoring safety precautions can result in short circuits, accidents, injuries, and
life-threatening electrical shocks.
x Never use a damaged outlet or a damaged power cable.
x Always plug the preheating system into a 120 Volt Ground Fault Circuit (GFI) wall outlet
that is properly protected against rain and other moisture.
x Always check the fuse protection of the 120 Volt power source before using the
connecting cable.
x Always use a 12 gauge or heavier heavy-duty extension cable that can be properly
grounded to a three-prong GFI outlet. The extension cable must not be longer than 100 ft
(30 meters).
x Check the cables for damage before every use. Never use a damaged cable. Damaged
cables must be replaced. See an authorized Volkswagen dealer or an authorized Volkswagen
Service Facility.
x Only use the cables provided.
x Always remove the connecting cable before starting the engine.
x Never attempt to alter or repair cables or other electrical components.
x Never let plugs or connectors come into contact with water, moisture, or any other fluids.
If the engine preheating system is used occasionally, test the GFI circuit breaker (Ground Fault
Circuit Interrupter) once a month. Test it once a week if the system is used regularly.

WARNING
Poor visibility increases the risk of collisions and other accidents that cause serious
personal injuries.
x Always make sure all windows are clear of ice, snow and condensation for good visibility
to the front, sides, and rear.
x Maximum heating output and defrosting performance are not possible until the engine has
reached operating temperature. Wait until you have good visibility before driving off.
x Always make sure you know how to properly use the climate control system as well as the
rear window defroster that you will need for good visibility.
x Never use air recirculation for long periods of time. When the air conditioner is off and
recirculation mode is on, condensation can quickly form on the windows and greatly reduce
visibility.
x Always switch off recirculation mode when it is not needed.
WARNING
Stale air causes driver fatigue and reduces driver alertness, which can cause accidents,
collisions and serious personal injury.
x Never switch off the fan for a long period of time and never use air recirculation a long
period of time because no fresh air will enter the passenger compartment.
NOTICE
x If you think the air conditioner is not working properly or may be damaged, switch it off to
help prevent more damage. Have the air conditioner checked by an authorized Volkswagen
dealer or an authorized Volkswagen Service Facility.
x Air conditioner repair requires specialized knowledge and special tools. Volkswagen
recommends that you see an authorized Volkswagen dealer or an authorized Volkswagen
Service Facility.
x Do not smoke when air recirculation is switched on. Smoke drawn into the ventilation
system can leave residue on the evaporator and on the dust and pollen active carbon filter,
resulting in permanent odors whenever the air conditioner is switched on.
If the air conditioner is switched off, the fresh outside air will not be dehumidified. To help keep
the windows from fogging over, Volkswagen recommends leaving the air conditioner (compressor)
switched on. Press the !

Emergency starting and starting the engine with a very weak vehicle battery or after the vehicle
battery has been replaced may change or delete system settings (including time, date, personal
convenience settings, and programming). Check the settings and correct as necessary once the
vehicle battery has built up a sufficient charge.

Air conditioner does not work
The air conditioner may not switch on for one of the following reasons:
x The engine is not running.
x The fan is switched off.
x The air conditioner fuse has blown.
x The outside air temperature is colder than about +38 °F (+3 °C).
x The air conditioner compressor has been temporarily switched off due to excessive engine coolant
temperature.
x There is another malfunction in the vehicle. Have the air conditioner checked by an authorized
Volkswagen dealer or authorized Volkswagen Service Facility.
Special considerations
When it is very hot and humid outside, water condensation can drip from the air conditioner
evaporator and form a puddle under the vehicle. This is normal and does not indicate a leak.
The climate control system adjusts the passenger compartment temperature as fast as possible
considering the outside temperature.
Due to residual moisture in the air conditioner, the windshield may fog up after the engine is
started. Switch on the windshield defroster to help evaporate the condensation as quickly as possible.
The air coming out of the vents flows through the passenger compartment and through the vents
under the rear window. Do not cover these slots with clothing or other things.

Refueling
Fuel capacities
Refueling checklist
The fuel filler flap is located on the rear right side of the vehicle.
More information:
x Exterior views
x Fuel
x Preparations for working in the engine compartment
WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Always make sure that the fuel filler cap is screwed on all the way. This helps keep fuel
from spilling out or evaporating.
x Fuel is highly flammable and explosive; it can cause severe burns and other severe
injuries.
x Failure to shut the engine off while refueling and/or to insert the pump nozzle all the way
into the fuel filler neck can cause fuel to overflow and to spray out. Fuel spray and
overflowing fuel are dangerous because they can cause fire and serious personal injury.
x During refueling, the engine and the ignition must be switched off for safety reasons.
x Never use a cellular telephone, CB radio, or other radio equipment while refueling. The
electromagnetic radiation can cause sparks that can ignite fuel vapors and cause a fire.
x Never get back into your vehicle while refueling. If in exceptional circumstances you must
get back in your vehicle while refueling, make certain that you close the door and touch metal
to discharge static electricity before touching the filler nozzle again. This helps avoid the
build-up of static electricity, which can cause sparks that can ignite fuel vapors released
during refueling.
x Never smoke or have an open flame (or sparks, cigarettes, or other smoldering objects)
anywhere in or near your vehicle when refueling or filling a portable fuel container.
x Follow all safety instructions and procedures that apply at the service station where you
refuel.
x Never spill fuel in the vehicle or the luggage compartment.
